80 M.0.A.L.MORCH’S REVIEW OF THE VERMETIDS. [Feb. 11, 
Serpuloides inoperculata, Gray, Fig. iv. p. 83; Gray, Guide,

. Serpulorbis inoperculata, Adams, Genera, i. p. 359. 
Hab. In mari Rubro, socialiter vivens prope vicum Tor lapidibus 
affixus, reperitur (Riippel). 
If this species can be generically distinguished, it would chiefly be 
on account of the heart-shaped shield over the head, like that of 
Siphonium maximum, represented by Quoy and Gaimard. It wants 
the pedal filaments, in common with Cladopoda and Limintina ; 
from the former it is distinguished by the circular tip of the 
metapodium, and from the latter by wanting the radiation of the 
foot. 
Subg. Lemintina, Risso, 1826. 
Lementina, Risso, Hist. iv. p. 433; Gray, Proc. Zool. Soc. 1847, 
p. 156, et Fig. iv. p. 83, 1850. 
Dr. Gray (Guide, p. 127) regards this genus as “ probably only a 
badly described and figured Serpuloides arenarius ;”’ but the shape 
of the metapodium seems so remarkable to me that I cannot believe 
that it is invented. The Vermetide have been so neglected that it 
is not impossible that a similar form may exist. 
24. TuyLacopes (LEMINTINA) CUVIERI, Risso. 
T. cylindrica, subspiralis, unilocularis, ad extremitatem posterio- 
rem clausa ; apertura rotunda (Risso). 
Animal limaciforme, postice vermiforme ; tentaculis subulatis ; 
oculi subsessiles, nigri; branchie albe super capite locate ; 
pes cylindricus, truncatus, superficie levi rubra, flavescente 
radiata, pallio fimbriato ruberrimo (Risso). 
Lemintina cuvieri, Risso, Hist. iv. p. 114, t. 2. f. 16-18; Gray, 
Fig. t. 57. f. 3, p. 83. 
Hab. Sur les rochers peu profonds (Risso). 
The figure of the shell does not show any longitudinal striz ; the 
description seems more natural than the figure, which is chiefly re- 
markable from the radiated metapodium dentated at the edge. 
Subg. Craporopa, Gray, 1850. 
Operculum none ; foot elongate, front end simple, hinder extre- 
mity oblong, clavate or subtruncate (Gray). 
Cladopoda, Gray, Fig. 1850, p. 83 ; Guide, p. 127, 
This genus is chiefly founded on the elongated shape of the hinder 
part of “the foot,” which, in the ‘ Voyage de l’Astrolabe,’ is repre- 
sented as fiddle-shaped (pes panduriformis), like the foot of Lacuna ; 
but, from analogy with the other Vermetide, it must be the tip of 
the metapodium unusually enlarged. In specimens in spirits of 7. 
polyphragma the metapodium is sometimes of an expanded shape ; I 
suppose therefore that this character is not of generic value. The
